This backend had no functionality, and with the recent support for GL on Desktop, which allows wgpu to run on older devices, there is no need to keep the backend.
This adds a way to allow a Vulkan driver which is non-compliant per VK_KHR_driver_properties to be enumerated. This is intended for testing new Vulkan drivers which are not Vulkan compliant yet.
### `DeviceExt::create_texture_with_data` Allows Mip-Major Data
Previously, `DeviceExt::create_texture_with_data` only allowed data to be provided in layer major order. There is now a `order` parameter which allows you to specify if the data is in layer major or mip major order.
### `expose-ids` feature now available unconditionally
This feature allowed you to call `global_id` on any wgpu opaque handle to get a unique hashable identity for the given resource. This is now available without the feature flag. By @cwfitzgerald in [#4841](https://github.com/gfx-rs/wgpu/pull/4841)
Wgpu now exposes backend feature for the Direct3D 12 (`dx12`) and Metal (`metal`) backend. These are enabled by default, but don't do anything when not targetting the corresponding OS. By @daxpedda in [#4815](https://github.com/gfx-rs/wgpu/pull/4815)
- Added `DownlevelFlags::VERTEX_AND_INSTANCE_INDEX_RESPECTS_RESPECTIVE_FIRST_VALUE_IN_INDIRECT_DRAW` to know if `@builtin(vertex_index)` and `@builtin(instance_index)` will respect the `first_vertex` / `first_instance` in indirect calls. If this is not present, both will always start counting from 0. Currently enabled on all backends except DX12. By @cwfitzgerald in [#4722](https://github.com/gfx-rs/wgpu/pull/4722)
- No longer validate surfaces against their allowed extent range on configure. This caused warnings that were almost impossible to avoid. As before, the resulting behavior depends on the compositor. By @wumpf in [#4796](https://github.com/gfx-rs/wgpu/pull/4796)
-`@builtin(instance_index)` now properly reflects the range provided in the draw call instead of always counting from 0. By @cwfitzgerald in [#4722](https://github.com/gfx-rs/wgpu/pull/4722).
- Naga's WGSL front end now allows operators to produce values with abstract types, rather than concretizing thir operands. By @jimblandy in [#4850](https://github.com/gfx-rs/wgpu/pull/4850) and [#4870](https://github.com/gfx-rs/wgpu/pull/4870).
- Naga's WGSL front and back ends now have experimental support for 64-bit floating-point literals: `1.0lf` denotes an `f64` value. There has been experimental support for an `f64` type for a while, but until now there was no syntax for writing literals with that type. As before, Naga module validation rejects `f64` values unless `naga::valid::Capabilities::FLOAT64` is requested. By @jimblandy in [#4747](https://github.com/gfx-rs/wgpu/pull/4747).
- Naga constant evaluation can now process binary operators whose operands are both vectors. By @jimblandy in [#4861](https://github.com/gfx-rs/wgpu/pull/4861).
- Naga's `cargo xtask validate` now runs validation jobs in parallel, using the [jobserver](https://crates.io/crates/jobserver) protocol to limit concurrency, and offers a `validate all` subcommand, which runs all available validation types. By @jimblandy in [#4902](https://github.com/gfx-rs/wgpu/pull/4902).
- Arcanization of wgpu core resources: By @gents83 in [#3626](https://github.com/gfx-rs/wgpu/pull/3626) and thanks also to @jimblandy, @nical, @Wumpf, @Elabajaba&@cwfitzgerald
- Removed Token and LifeTime related management
- Removed RefCount and MultiRefCount in favour of using only Arc internal reference count
- Removing mut from resources and added instead internal members locks on demand or atomics operations
- Resources now implement Drop and destroy stuff when last Arc resources is released
- Resources hold an Arc in order to be able to implement Drop
- Resources have an utility to retrieve the id of the resource itself
- Remove all guards and just retrive the Arc needed on-demand to unlock registry of resources asap
- Verify correct resources release when unused or not needed
- Check Web and Metal compliation (thanks to @niklaskorz)
- Fix tests on all platforms
- Test a multithreaded scenario
- Storage is now holding only user-land resources, but Arc is keeping refcount for resources
- When user unregister a resource, it's not dropped if still in use due to refcount inside wgpu
- IdentityManager is now unique and free is called on resource drop instead of storage unregister
- Identity changes due to Arcanization and Registry being just the user reference
-`TextureFormat::block_size` is deprecated, use `TextureFormat::block_copy_size` instead: By @wumpf in [#4647](https://github.com/gfx-rs/wgpu/pull/4647)
- Rename of `DispatchIndirect`, `DrawIndexedIndirect`, and `DrawIndirect` types in the `wgpu::util` module to `DispatchIndirectArgs`, `DrawIndexedIndirectArgs`, and `DrawIndirectArgs`. By @cwfitzgerald in [#4723](https://github.com/gfx-rs/wgpu/pull/4723).
- Make the size parameter of `encoder.clear_buffer` an `Option<u64>` instead of `Option<NonZero<u64>>`. By @nical in [#4737](https://github.com/gfx-rs/wgpu/pull/4737)
- Reduce the `info` log level noise. By @nical in [#4769](https://github.com/gfx-rs/wgpu/pull/4769), [#4711](https://github.com/gfx-rs/wgpu/pull/4711) and [#4772](https://github.com/gfx-rs/wgpu/pull/4772)
- Rename `features`&`limits` fields of `DeviceDescriptor` to `required_features`&`required_limits`. By @teoxoy in [#4803](https://github.com/gfx-rs/wgpu/pull/4803)
It is now possible to safely create a `wgpu::Surface` with `Surface::create_surface()` by letting `Surface` hold a lifetime to `window`.
Passing an owned value `window` to `Surface` will return a `Surface<'static>`. Shared ownership over `window` can still be achieved with e.g. an `Arc`. Alternatively a reference could be passed, which will return a `Surface<'window>`.
`Surface::create_surface_from_raw()` can be used to continue producing a `Surface<'static>` without any lifetime requirements over `window`, which also remains `unsafe`.
- Remove `span` and `validate` features. Always fully validate shader modules, and always track source positions for use in error messages. By @teoxoy in [#4706](https://github.com/gfx-rs/wgpu/pull/4706)
- Introduce a new `Scalar` struct type for use in Naga's IR, and update all frontend, middle, and backend code appropriately. By @jimblandy in [#4673](https://github.com/gfx-rs/wgpu/pull/4673).
- Add partial support for WGSL abstract types (@jimblandy in [#4743](https://github.com/gfx-rs/wgpu/pull/4743), [#4755](https://github.com/gfx-rs/wgpu/pull/4755)).
-`BufferMappedRange` trait is now `WasmNotSendSync`, i.e. it is `Send`/`Sync` if not on wasm or `fragile-send-sync-non-atomic-wasm` is enabled. By @wumpf in [#4818](https://github.com/gfx-rs/wgpu/pull/4818)
- Allow calling `BufferSlice::get_mapped_range` multiple times on the same buffer slice (instead of throwing a Javascript exception): By @DouglasDwyer in [#4726](https://github.com/gfx-rs/wgpu/pull/4726)
- Make module compaction preserve the module's named types, even if they are unused. By @jimblandy in [#4734](https://github.com/gfx-rs/wgpu/pull/4734).
- When reading GLSL, fix the argument types of the double-precision floating-point overloads of the `dot`, `reflect`, `distance`, and `ldexp` builtin functions. Correct the WGSL generated for constructing 64-bit floating-point matrices. Add tests for all the above. By @jimblandy in [#4684](https://github.com/gfx-rs/wgpu/pull/4684).
- Allow Naga's IR types to represent matrices with elements elements of any scalar kind. This makes it possible for Naga IR types to represent WGSL abstract matrices. By @jimblandy in [#4735](https://github.com/gfx-rs/wgpu/pull/4735).
- When evaluating const-expressions and generating SPIR-V, properly handle `Compose` expressions whose operands are `Splat` expressions. Such expressions are created and marked as constant by the constant evaluator. By @jimblandy in [#4695](https://github.com/gfx-rs/wgpu/pull/4695).
- Preserve the source spans for constants and expressions correctly across module compaction. By @jimblandy in [#4696](https://github.com/gfx-rs/wgpu/pull/4696).
- hello-compute example fix failure with "wgpu error: Validation Error" if arguments are missing by @vilcans in [#4939](https://github.com/gfx-rs/wgpu/pull/4939)
- Made the examples page not crash on Chrome on Android, and responsive to screen sizes by @Dinnerbone in [#4958](https://github.com/gfx-rs/wgpu/pull/4958)
- Always use HLSL 2018 when using DXC to compile HLSL shaders. By @daxpedda in [#4629](https://github.com/gfx-rs/wgpu/pull/4629)
#### Metal
- In Metal Shading Language output, fix issue where local variables were sometimes using variable names from previous functions. By @DJMcNab in [#4594](https://github.com/gfx-rs/wgpu/pull/4594)
We now support OpenGL on Windows! This brings support for a vast majority of the hardware that used to be covered by our DX11 backend. As of this writing we support OpenGL 3.3+, though there are efforts to reduce that further.
This allows us to cover the last 12 years of Intel GPUs (starting with Ivy Bridge; aka 3xxx), and the last 16 years of AMD (starting with Terascale; aka HD 2000) / NVidia GPUs (starting with Tesla; aka GeForce 8xxx).
### Timestamp Queries Supported on Metal and OpenGL
Timestamp queries are now supported on both Metal and Desktop OpenGL. On Apple chips on Metal, they only support timestamp queries in command buffers or in the renderpass descriptor,
Addition of the `TimestampWrites` type to compute and render pass descriptors to allow profiling on tilers which do not support timestamps inside passes.
The instance descriptor grew two more fields: `flags` and `gles_minor_version`.
`flags` allow you to toggle the underlying api validation layers, debug information about shaders and objects in capture programs, and the ability to discard lables
`gles_minor_version` is a rather niche feature that allows you to force the GLES backend to use a specific minor version, this is useful to get ANGLE to enable more than GLES 3.0.
```diff
let instance = wgpu::Instance::new(InstanceDescriptor {
Our testing harness was completely revamped and now automatically runs against all gpus in the system, shows the expected status of every test, and is tolerant to flakes.
Additionally, we have filled out our CI to now run the latest versions of WARP and Mesa. This means we can test even more features on CI than before.
By @cwfitzgerald in [#3873](https://github.com/gfx-rs/wgpu/pull/3873)
- Add validation in accordance with WebGPU `setViewport` valid usage for `x`, `y` and `this.[[attachment_size]]`. By @James2022-rgb in [#4058](https://github.com/gfx-rs/wgpu/pull/4058)
-`wgpu::CreateSurfaceError` and `wgpu::RequestDeviceError` now give details of the failure, but no longer implement `PartialEq` and cannot be constructed. By @kpreid in [#4066](https://github.com/gfx-rs/wgpu/pull/4066) and [#4145](https://github.com/gfx-rs/wgpu/pull/4145)

- Let the `"strict_asserts"` feature enable check that wgpu-core's lock-ordering tokens are unique per thread. By @jimblandy in [#4258]([https://github.com/gfx-rs/wgpu/pull/4258])
-`DeviceLostClosure` callback mechanism provided so user agents can resolve `GPUDevice.lost` Promises at the appropriate time by @bradwerth in [#4645](https://github.com/gfx-rs/wgpu/pull/4645)
- Don't bother calling `vkFreeCommandBuffers` when `vkDestroyCommandPool` will take care of that for us. By @jimblandy in [#4059](https://github.com/gfx-rs/wgpu/pull/4059)
-`Queue::on_submitted_work_done` callbacks will now always be called after all previous `BufferSlice::map_async` callbacks, even when there are no active submissions. By @cwfitzgerald in [#4036](https://github.com/gfx-rs/wgpu/pull/4036).
- Fix `clear` texture views being leaked when `wgpu::SurfaceTexture` is dropped before it is presented. By @rajveermalviya in [#4057](https://github.com/gfx-rs/wgpu/pull/4057).
- Add `Feature::SHADER_UNUSED_VERTEX_OUTPUT` to allow unused vertex shader outputs. By @Aaron1011 in [#4116](https://github.com/gfx-rs/wgpu/pull/4116).

- Fix enabling `wgpu::Features::PARTIALLY_BOUND_BINDING_ARRAY` not being actually enabled in vulkan backend. By @39ali in[#3772](https://github.com/gfx-rs/wgpu/pull/3772).
- Don't pass `vk::InstanceCreateFlags::ENUMERATE_PORTABILITY_KHR` unless the `VK_KHR_portability_enumeration` extension is available. By @jimblandy in[#4038](https://github.com/gfx-rs/wgpu/pull/4038).
- Created `wgpu-example::utils` module to contain misc functions and such that are common code but aren't part of the example framework. Add to it the functions `output_image_wasm` and `output_image_native`, both for outputting `Vec<u8>` RGBA images either to the disc or the web page. By @JustAnotherCodemonkey in [#3885](https://github.com/gfx-rs/wgpu/pull/3885).
- Removed `capture` example as it had issues (did not run on wasm) and has been replaced by `render-to-texture` (see above). By @JustAnotherCodemonkey in [#3885](https://github.com/gfx-rs/wgpu/pull/3885).
- Fix x11 hang while resizing on vulkan. @Azorlogh in [#4184](https://github.com/gfx-rs/wgpu/pull/4184).
## v0.17.1 (2023-09-27)
### Added/New Features
- Add `get_mapped_range_as_array_buffer` for faster buffer read-backs in wasm builds. By @ryankaplan in [#4042] (https://github.com/gfx-rs/wgpu/pull/4042).
### Bug Fixes
#### DX12
- Fix panic on resize when using DX12. By @cwfitzgerald in [#4106](https://github.com/gfx-rs/wgpu/pull/4106)
#### Vulkan
- Suppress validation error caused by OBS layer. This was also fixed upstream. By @cwfitzgerald in [#4002](https://github.com/gfx-rs/wgpu/pull/4002)
- Work around bug in nvidia's vkCmdFillBuffer implementation. By @cwfitzgerald in [#4132](https://github.com/gfx-rs/wgpu/pull/4132).
This is the first release that featured `wgpu-info` as a binary crate for getting information about what devices wgpu sees in your system. It can dump the information in both human readable format and json.
Up until this point, wgpu has made the assumption that threads do not exist on wasm. With the rise of libraries like [`wasm_thread`](https://crates.io/crates/wasm_thread) making it easier and easier to do wasm multithreading this assumption is no longer sound. As all wgpu objects contain references into the JS heap, they cannot leave the thread they started on.
As we understand that this change might be very inconvenient for users who don't care about wasm threading, there is a crate feature which re-enables the old behavior: `fragile-send-sync-non-atomic-wasm`. So long as you don't compile your code with `-Ctarget-feature=+atomics`, `Send` and `Sync` will be implemented again on wgpu types on wasm. As the name implies, especially for libraries, this is very fragile, as you don't know if a user will want to compile with atomics (and therefore threads) or not.
By @daxpedda in [#3691](https://github.com/gfx-rs/wgpu/pull/3691)
#### Power Preference is now optional
The `power_preference` field of `RequestAdapterOptions` is now optional. If it is `PowerPreference::None`, we will choose the first available adapter, preferring GPU adapters over CPU adapters.
By @Aaron1011 in [#3903](https://github.com/gfx-rs/wgpu/pull/3903)
Removed the backend_bits parameter from `initialize_adapter_from_env` and `initialize_adapter_from_env_or_default`. If you want to limit the backends used by this function, only enable the wanted backends in the instance.
- Added support for importing external buffers using `buffer_from_raw` (Dx12, Metal, Vulkan) and `create_buffer_from_hal`. By @AdrianEddy in [#3355](https://github.com/gfx-rs/wgpu/pull/3355)
- Work around [Vulkan-ValidationLayers#5671](https://github.com/KhronosGroup/Vulkan-ValidationLayers/issues/5671) by ignoring reports of violations of [VUID-vkCmdEndDebugUtilsLabelEXT-commandBuffer-01912](https://registry.khronos.org/vulkan/specs/1.3-extensions/html/vkspec.html#VUID-vkCmdEndDebugUtilsLabelEXT-commandBuffer-01912). By @jimblandy in [#3809](https://github.com/gfx-rs/wgpu/pull/3809).
- Add `get_mapped_range_as_array_buffer` for faster buffer read-backs in wasm builds. By @ryankaplan in [#4042] (https://github.com/gfx-rs/wgpu/pull/4042).
- Better documentation for draw, draw_indexed, set_viewport and set_scissor_rect. By @genusistimelord in [#3860](https://github.com/gfx-rs/wgpu/pull/3860)
- Validate that `descriptor.usage` is not empty in `create_buffer` by @nical in [#3928](https://github.com/gfx-rs/wgpu/pull/3928)
- Update `max_bindings_per_bind_group` limit to reflect spec changes by @ErichDonGubler and @nical in [#3943](https://github.com/gfx-rs/wgpu/pull/3943) [#3942](https://github.com/gfx-rs/wgpu/pull/3942)
- Add better docs for `Limits`, listing the actual limits returned by `downlevel_defaults` and `downlevel_webgl2_defaults` by @JustAnotherCodemonkey in [#3988](https://github.com/gfx-rs/wgpu/pull/3988)
- Fix OpenGL/EGL backend not respecting non-sRGB texture formats in `SurfaceConfiguration`. by @liquidev in [#3817](https://github.com/gfx-rs/wgpu/pull/3817)
- Fix Multiview to disable validation of TextureViewDimension and ArrayLayerCount. By @MalekiRe in [#3779](https://github.com/gfx-rs/wgpu/pull/3779#issue-1713269437).
#### Vulkan
- Fix incorrect aspect in barriers when using emulated Stencil8 textures. By @cwfitzgerald in [#3833](https://github.com/gfx-rs/wgpu/pull/3833).
- Implement depth-clip-control using depthClamp instead of VK_EXT_depth_clip_enable. By @AlbinBernhardssonARM [#3892](https://github.com/gfx-rs/wgpu/pull/3892).
- Fix enabling `wgpu::Features::PARTIALLY_BOUND_BINDING_ARRAY` not being actually enabled in vulkan backend. By @39ali in[#3772](https://github.com/gfx-rs/wgpu/pull/3772).
- Make the `Id` type that is exposed when using the `expose-ids` feature implement `Send` and `Sync` again. This was unintentionally changed by the v0.16.0 release and is now fixed.
- Increase the `max_storage_buffers_per_shader_stage` and `max_storage_textures_per_shader_stage` limits based on what the hardware supports. by @Elabajaba in [#3798]https://github.com/gfx-rs/wgpu/pull/3798
The `TextureFormat::describe` function was removed in favor of separate functions: `block_dimensions`, `is_compressed`, `is_srgb`, `required_features`, `guaranteed_format_features`, `sample_type` and `block_size`.
Buffers used as the `destination` argument of `CommandEncoder::resolve_query_set` now have to contain the `QUERY_RESOLVE` usage instead of the `COPY_DST` usage.
```diff
let destination = device.create_buffer(&wgpu::BufferDescriptor {
- Change type of `mip_level_count` and `array_layer_count` (members of `TextureViewDescriptor` and `ImageSubresourceRange`) from `Option<NonZeroU32>` to `Option<u32>`. By @teoxoy in [#3445](https://github.com/gfx-rs/wgpu/pull/3445)
- Change type of `bytes_per_row` and `rows_per_image` (members of `ImageDataLayout`) from `Option<NonZeroU32>` to `Option<u32>`. By @teoxoy in [#3529](https://github.com/gfx-rs/wgpu/pull/3529)
- On Web, `Instance::create_surface_from_canvas()` and `create_surface_from_offscreen_canvas()` now take the canvas by value. By @daxpedda in [#3690](https://github.com/gfx-rs/wgpu/pull/3690)
- Added feature flags for ray-tracing (currently only hal): `RAY_QUERY` and `RAY_TRACING`@daniel-keitel (started by @expenses) in [#3507](https://github.com/gfx-rs/wgpu/pull/3507)
#### Vulkan
- Implemented basic ray-tracing api for acceleration structures, and ray-queries @daniel-keitel (started by @expenses) in [#3507](https://github.com/gfx-rs/wgpu/pull/3507)
- Added basic ray-tracing api for acceleration structures, and ray-queries @daniel-keitel (started by @expenses) in [#3507](https://github.com/gfx-rs/wgpu/pull/3507)
- Don't include ANSI terminal color escape sequences in shader module validation error messages. By @jimblandy in [#3591](https://github.com/gfx-rs/wgpu/pull/3591)
- Error in native when using a filterable `TextureSampleType::Float` on a multisample `BindingType::Texture`. By @mockersf in [#3686](https://github.com/gfx-rs/wgpu/pull/3686)
- On Web, the size of the canvas is adjusted when using `Surface::configure()`. If the canvas was given an explicit size (via CSS), this will not affect the visual size of the canvas. By @daxpedda in [#3690](https://github.com/gfx-rs/wgpu/pull/3690)
-`copyTextureToTexture` src/dst aspects must both refer to all aspects of src/dst format. By @teoxoy in [#3431](https://github.com/gfx-rs/wgpu/pull/3431)
- Validate before extracting texture selectors. By @teoxoy in [#3487](https://github.com/gfx-rs/wgpu/pull/3487)
- Fix fatal errors (those which panic even if an error handler is set) not including all of the details. By @kpreid in [#3563](https://github.com/gfx-rs/wgpu/pull/3563)
- Validate shader location clashes. By @emilk in [#3613](https://github.com/gfx-rs/wgpu/pull/3613)
- Fix surfaces not being dropped until exit. By @benjaminschaaf in [#3647](https://github.com/gfx-rs/wgpu/pull/3647)
- Fix handling of `None` values for `depth_ops` and `stencil_ops` in `RenderPassDescriptor::depth_stencil_attachment`. By @niklaskorz in [#3660](https://github.com/gfx-rs/wgpu/pull/3660)
- Fix `copy_external_image_to_texture`, `copy_texture_to_texture` and `copy_buffer_to_texture` not taking the specified index into account if the target texture is a cube map, 2D texture array or cube map array. By @daxpedda [#3641](https://github.com/gfx-rs/wgpu/pull/3641)
- Fix disabling of vertex attributes with non-consecutive locations. By @Azorlogh in [#3706](https://github.com/gfx-rs/wgpu/pull/3706)
#### Metal
- Fix metal erroring on an `array_stride` of 0. By @teoxoy in [#3538](https://github.com/gfx-rs/wgpu/pull/3538)
-`create_texture` returns an error if `new_texture` returns NULL. By @jinleili in [#3554](https://github.com/gfx-rs/wgpu/pull/3554)
- Fix shader bounds checking being ignored. By @FL33TW00D in [#3603](https://github.com/gfx-rs/wgpu/pull/3603)
#### Vulkan
- Treat `VK_SUBOPTIMAL_KHR` as `VK_SUCCESS` on Android due to rotation issues. By @James2022-rgb in [#3525](https://github.com/gfx-rs/wgpu/pull/3525)
### Examples
- Use `BufferUsages::QUERY_RESOLVE` instead of `BufferUsages::COPY_DST` for buffers used in `CommandEncoder::resolve_query_set` calls in `mipmap` example. By @JolifantoBambla in [#3489](https://github.com/gfx-rs/wgpu/pull/3489)
## v0.15.3 (2023-03-22)
### Bug Fixes
#### Metal
- Fix incorrect mipmap being sampled when using `MinLod <= 0.0` and `MaxLod >= 32.0` or when the fragment shader samples different Lods in the same quad. By @cwfitzgerald in [#3610](https://github.com/gfx-rs/wgpu/pull/3610).
#### GLES
- Fix `Vertex buffer is not big enough for the draw call.` for ANGLE/Web when rendering with instance attributes on a single instance. By @wumpf in [#3596](https://github.com/gfx-rs/wgpu/pull/3596)
- Enable `WEBGL_debug_renderer_info` before querying unmasked vendor/renderer to avoid crashing on emscripten in [#3519](https://github.com/gfx-rs/wgpu/pull/3519)
`Instance::create_surface()` now returns `Result<Surface, CreateSurfaceError>` instead of `Surface`. This allows an error to be returned if the given window is a HTML canvas and obtaining a WebGPU or WebGL 2 context fails. (No other platforms currently report any errors through this path.) By @kpreid in [#3052](https://github.com/gfx-rs/wgpu/pull/3052/)
A new api, `Queue::copy_external_image_to_texture`, allows you to create wgpu textures from various web image primitives. Specificically from `HtmlVideoElement`, `HtmlCanvasElement`, `OffscreenCanvas`, and `ImageBitmap`. This provides multiple low-copy ways of interacting with the browser. WebGL is also supported, though WebGL has some additional restrictions, represented by the `UNRESTRICTED_EXTERNAL_IMAGE_COPIES` downlevel flag. By @cwfitzgerald in [#3288](https://github.com/gfx-rs/wgpu/pull/3288)
#### Instance creation now takes `InstanceDescriptor` instead of `Backends`
`Instance::new()` and `hub::Global::new()` now take an `InstanceDescriptor` struct which cointains both the existing `Backends` selection as well as a new `Dx12Compiler` field for selecting which Dx12 shader compiler to use.
```diff
- let instance = Instance::new(wgpu::Backends::all());
+ let instance = Instance::new(wgpu::InstanceDescriptor {
+ backends: wgpu::Backends::all(),
+ dx12_shader_compiler: wgpu::Dx12Compiler::Fxc,
+ });
```
`Instance` now also also implements `Default`, which uses `wgpu::Backends::all()` and `wgpu::Dx12Compiler::Fxc` for `InstanceDescriptor`
```diff
- let instance = Instance::new(wgpu::InstanceDescriptor {
- backends: wgpu::Backends::all(),
- dx12_shader_compiler: wgpu::Dx12Compiler::Fxc,
- });
+ let instance = Instance::default();
```

The new `view_formats` field in the `TextureDescriptor` is used to specify a list of formats the texture can be re-interpreted to in a texture view. Currently only changing srgb-ness is allowed (ex. `Rgba8Unorm`<=> `Rgba8UnormSrgb`).
Via the `TEXTURE_ADAPTER_SPECIFIC_FORMAT_FEATURES` feature, MSAA x2 and x8 are now supported on textures. To query for x2 or x8 support, enable the feature and look at the texture format flags for the texture format of your choice.

#### DXC Shader Compiler Support for DX12
You can now choose to use the DXC compiler for DX12 instead of FXC. The DXC compiler is faster, less buggy, and allows for new features compared to the old, unmaintained FXC compiler.
You can choose which compiler to use at `Instance` creation using the `dx12_shader_compiler` field in the `InstanceDescriptor` struct. Note that DXC requires both `dxcompiler.dll` and `dxil.dll`, which can be downloaded from https://github.com/microsoft/DirectXShaderCompiler/releases. Both .dlls need to be shipped with your application when targeting DX12 and using the `DXC` compiler. If the .dlls can't be loaded, then it will fall back to the FXC compiler. By @39ali and @Elabajaba in [#3356](https://github.com/gfx-rs/wgpu/pull/3356)
The DX12 backend can now suballocate buffers and textures from larger chunks of memory, which can give a significant increase in performance (in testing a 100x improvement has been seen in a simple scene with 200 `write_buffer` calls per frame, and a 1.4x improvement in [Bistro using Bevy](https://github.com/vleue/bevy_bistro_playground)).
Previously `wgpu-hal`'s DX12 backend created a new heap on the GPU every time you called `write_buffer` (by calling `CreateCommittedResource`), whereas now it uses [`gpu_allocator`](https://crates.io/crates/gpu-allocator) to manage GPU memory (and calls `CreatePlacedResource` with a suballocated heap). By @Elabajaba in [#3163](https://github.com/gfx-rs/wgpu/pull/3163)
#### Backend selection by features in wgpu-core
Whereas `wgpu-core` used to automatically select backends to enable
based on the target OS and architecture, it now has separate features
to enable each backend:
- "metal", for the Metal API on macOS and iOS
- "vulkan", for the Vulkan API (Linux, some Android, and occasionally Windows)
- "dx12", for Microsoft's Direct3D 12 API
- "gles", OpenGL ES, available on many systems
- "dx11", for Microsoft's Direct3D 11 API
None are enabled by default, but the `wgpu` crate automatically
selects these features based on the target operating system and
architecture, using the same rules that `wgpu-core` used to, so users
of `wgpu` should be unaffected by this change. However, other crates
using `wgpu-core` directly will need to copy `wgpu`'s logic or write
their own. See the `[target]` section of `wgpu/Cargo.toml` for
details.
Similarly, `wgpu-core` now has `emscripten` and `renderdoc` features
that `wgpu` enables on appropriate platforms.
In previous releases, the `wgpu-core` crate decided which backends to
support. However, this left `wgpu-core`'s users with no way to
override those choices. (Firefox doesn't want the GLES back end, for
example.) There doesn't seem to be any way to have a crate select
backends based on target OS and architecture that users of that crate
can still override. Default features can't be selected based on the
target, for example. That implies that we should do the selection as
late in the dependency DAG as feasible. Having `wgpu` (and
`wgpu-core`'s other dependents) choose backends seems like the best
option.
